8 Typical applications
The following figure shows a typical automotive lighting application (only one vehicle corner) using an external PWM clock from the
main MCU. A redundancy circuitry has been implemented to substitute light control (from MCU to watchdog) in case of a Fail-safe
condition.
It is recommended to locate a 22 nF decoupling capacitor to the module connector.
